I am trying to install a program that I need to use for my research, but I am running into issues. The program is called "hmf," and I can sucessfully install it using pip install hmf. However, when I try to import a module, I get an issue: This image shows the error message I get, which is

ImportError: cannot import name 'CAMB' from 'hmf.density_field.transfer_models' (/Users/cammienorton/opt/anaconda3/lib/python3.8/site-packages/hmf/density_field/transfer_models.py)

As per the online suggestion on https://hmf.readthedocs.io/en/latest/installation.html I have tried running

conda install -c conda-forge numpy scipy astropy camb

and I don't get any error messages. Does anyone have any idea what is going on?

UPDATE: I tried pip install CAMB and received the following error message, which says that there was an error while building the wheel.

  • Possibly `pip` does not refer to the Python distribution you are using. You can check the version of `pip` and its path using the command `pip --version` – gofvonx Apr 03 '21 at 17:18
  • @gofvonx I checked this, and ensured that I have the most updated version of pip. I still get the same error messages. – ccalculates Apr 03 '21 at 20:03

  • I tried this, and received another error message, that says an error occurred while building wheel for CAMB (setup.py). Any idea as to what this means? – ccalculates Apr 03 '21 at 19:58
  • I have updated the question to include the whole error message. – ccalculates Apr 03 '21 at 20:05
